VB - Has any of you guys experienced THIS???

Using Visual Basic Express 2010 and what i´m facing right now is that Avast is marking many of my apps as viruses.

I know they are false positive since i made them myself and i also know the same thing is happening to many small developers/official game installers.

It seems to be caused by Avast FileRep system that works on-execute only and marks new files suspicious based on various factors (age,reputation,popularity,code). Giving a "FileRepMetagen" warning and moving .exe to quarantine any time you try to download it from the internet or launch it.

Have you faced something similar? Is there something i could improve in VB settings to make it more Avast friendly? How would you deal with it? Avast is ruining my plans and reading their forums i see other people as angry as i am right now!

If you have experience with this or with making apps, PLEASE do let me know your thoughts on this!!!

Thanks,

Make a completely blank form and see if Avast detects that before you do anything else.

Thanks for the suggestion, but no it doesn´t. It happens in 1-2 days after promotion. My theory is that since apps are new, not signed and Avast detects an app suddenly on many computers, it triggers its FileRep feature and starts setting off the alarm. You can find many cases in Avast forum for legit launchers/installers and small devs complaining.

I´m just thinking that maybe there is something i can do to make it better. Has any of you promoted an app on larger scale (the way people have to launch it) and got away with it? Yeah, i can make a new build daily for every app, but it´s going to be quite time-consuming...

All of my apps get detected as WS.Reputation.1 by Norton and I still earn, so if one antivirus detects it, you might be better off ignoring it.

You have better luck than I since less people use Norton Cool. Avast is really popular and I´m sure it´s costing me money...You know any tricks how to make VB apps more AV friendly? I would be happy if only Norton detected it.

There really is not much you can do unless you call Avast up and ask for an appeal O.o

I've had that problem before if I included a term like "krack", "keygen", "hacker", etc in the file attributes of that application.

Scan it on virustotal and see which anti virus programs detect it.

Thanks, this could help. What do you use now if i may ask? Are you avoiding certain words?

Yeah, if it were that simple. Unfortunately, Avast holds 2nd position after Microsoft in worldwide AV market share.

It is detected by Avast and a few small AVs that probably are just following the big daddy :)

You should first check what kind of virus the AV classifies your program as. For example Trojan.Dropper, Trojan.Downloader,WS.Reputation, etc. Make sure the program doesn't download anything without user confirmation (you should place a Yes/No messagebox). As mentioned you should avoid using 'hacking' terms in the program's assembly. Keep in mind that .NET is not compiled to native code and can be easily decompiled or analyzed by antivirus' heuristics.
